Answer 1

Answer :-

Given :-

•) Time taken by person A to complete the task is = 7.5 minutes

•) Time taken by person B to complete the same task is = 17.5 minutes

To find :-

•) The ratio of the time taken by A and B in simplest whole number ?

Solution :-

Ratio = Time taken by A / Time taken by B

=> Ratio = 7.5 / 17.5

=> Ratio = 0.428

Answer 2

GIVEN :

• A person 'A' can complete a task in 7.5 minutes.

• Whereas the another person 'B' complete a task in 17:5 minutes.

TO FIND :

• The ratio of time taken by the person 'A' and person 'B' = ? (Simplest whole number form).

STEP - BY - STEP EXPLANATION :

$= > ratio = \frac{time \: taken \: by \: the \: person <strong>\: A \:</strong> to \: complete \: the \: task \: }{the \: time \: taken \: by \: person \: <strong>B \:</strong> to \: complete \: the \: same \: task}$

$= > ratio = \frac{7.5}{17.5} = 0.428$

Hence, Here the time taken by Person 'A' and person 'B' = 0.428
